SHOCK-Ansonziien Fon BATTERIES.

. Application filed August 20, 1915. Seria41VNo.46,'577.

Be it known that we, 'Fiirznnuieii N. BossoN and Lvsaxinzn B.Anirs'rnoNG, both citizehsof the lnited States, and residents et'Calumet, in the county of Houghton and declare that the following isafull7 clear,

'and exact description thereof.

This invention relates to the subject of f Storage and otherbatteriemiaiid the )rirubber that bears on the coverhV 4.

mary aim of the invention is to provite a novel type of battery jar forthe electrodes j that will cushion said electrodes against damage due tovibrations transmitted to the battery ease, the jar being i'ormedof'eush- -inning material that will vieldablv engage the electrodes.4Another object ot' the lvention is to provide novel means for cushioningtwoor more of the l'iattery jars from each other and also to providemeans tor i cushioning the jars from the battery case.

Referring lto the accornj'ninying' drawings by numerals, -1 designatesthe battery case having the sets ofeleetrodes therein, ,theA nvbatteries are .subjected to shocks 4and jarselectrodes being inclosedbythe jars provided with the covers '4 that are held in position to closethe jars bythe clamping:J bar 5 depending irom the cover of the case andhaving a cushion Lof .soft material such as The jars 3 are preferablyformed oi' comparatively stiff material s-uch as rubber that ishardefied. and the side portions or walls of the jars abut theelectrodes- ',l`he bottomsiof the jars may beprovided with a rib or ribs7 of aol't rubber. the ribs4 projecting;r in wardl v and ei{agziiiggl'f'tl'ubottoni-admis of the electrodes 2.

eI-ably formed of soft rubberhaving aliaro, rubber backing vulcanizedthereto, ythe covers beingalso providerl \\'ith inwardly vprojecting,rsofi; rubber ribs 8 that bear on the hangers for the electrodes. Thecovers fr are provided with a centra-l vent opening 9 having.'` branches10 that extend through thev backing. The case 1 is provided withw.r-cntral opening 11 for venting purposes, the inlet end o said openingbeing surrounded by a cage 12 having .side inlets 13. The

Acover-.fs l1 4are also provided with suit-able openings y14 throughwhich the electrode y liangers 15 project.

As if, shown more clearly in Fig. 1 of the dra wings, the jars fi have a.shock absorbing sheet 1G interposed between them, and similar strips orsheets 17 are interposed between the jars and the sides and ends of therase 1. And the jars 5l preferably ot the same shape and material,

each hai-ini;r ,their outer surfaces transversely corrugated. asindicated at 19 and having: the 4transverse openings 20 extending` seaton a b0tt0m oi' shock absorbing inaterial 18.

The

The shock. absorbing .sheets are. preferably of softrubber and being of cellular formation it ivill be readily apparent thatthey will etici-tively shield the' jars from vibratory and other shocksthat may be transmitted to the case 1.

'l`lie shock alista-hing arrangement for batteries is of specialfutility in connection with motor and ,other vehicleS wherein theincidental to the travelY of. the vehicle and Vthe running of theengine.
